My fascination with the Swedish royal family began when, as a young teen, I read the historical novel Desiree by Anne-Marie Selinko. It's the story of Desiree Clary, the daughter of a French silk merchant, who was the wife of that elected king, Jean-Baptist Bernadotte. Fairly modest beginnings for the house of Bernadotte although they married into several much older royal houses along the way to the 20th Century.
